MAIN CHARACTERISTICS

V3EC servocontrols have been designed for use on domestic heating and cooling systems, where compact dimensions and ease of assembly are required. The closing force of the valve stem is guaranteed by a spring coupled to a wax expansion element. To motorise the manually controlled shutter valves, predisposed to be controlled by these servocontrols, it is sufficient to unscrew the manual knob completely and screw the ring nut of the actuator for the quick coupling to the servocontrol. All this is done without having to drain the system (see table 3 for the valves predisposed for these servocontrols).
